Hi everybody!
I know there are bound to be lots of new people. I just wanted to give you some encouragement. I quit 10 months ago and:
1) no you are not crazy
2) No, you will not feel crazy forever, only for about 6 months.
3) Yes, If you're patient enough you'll be less crazy if you use gum or lozenges.
4) No, you don't have to gain weight. I lost 30 pounds afer I quit. With my new found lung capacity I decided to train for a half marathon. It kept me busy, kept the quit smoking blues at bay, and made me fitter than I've ever been. Now I am running a full marathon in 2 weeks and I have never been this healthy.
I started my journey 2 years ago over 100 pounds over weight and smoking a pack a day. That year my resolution was lose weight. Last year it was quit smoking. This year it's get rich. I figure I might as well go 3 for 3.
Best advice:
You get what you expect, not what you want. Raise your expectations
You never fail until you stop trying. Just keep going.
Good luck.
